Czeslaw Milosz is a Czech poet and playwright. Milan Kundera, also Czech,
is the author of The Unbearable Lightness of Being, among other novels.

As an aside, here's a small item on Milosz I found on my disk:

'Milosz, the Czech poet, in a Times interview used silkworms to refer
to his need to write afresh rather than on something he had before:

"...we see him spinning a thread out of himself like a silkworm:
he makes cocoons that lose their initial softness, becoming hard,
almost crystalline structures in which he can no longer live,
and so he has to move out. And again he makes a cocoon,
and again it hardens and becomes alien to him."'

This also may illustrate why some people are driven to spade their
lives over every so often. Norm
